✨ SPAMALYZE ✨

okay bestie, so this is spamalyze — a Perl script from the User Contributed Perl Documentation section of the manual (that's the 1p vibe, iykyk). It's giving "let me drag your entire mbox through a pile of Realtime Blackhole Lists and tell you who's sus." 💅

🎀 NAME 🎀

spamalyze — Apply multiple Realtime Blackhole Lists to all messages in an mbox

🦋 SYNOPSIS 🦋

spamalyze myspam.mbox

spamalyze goodstuff.mbox

tail -3000 some.mbox | spamalzse
yes, that last one literally says spamalzse. That's not me, that's the manual. Copy-paste it exactly like that and do not come for me. 😭

🌸 DESCRIPTION 🌸

So here's the tea, bestie. Spamalyze reads in an mbox file that's holding a whole bunch of mail messages, and then it looks up the originating server of each message against multiple Realtime Blackhole Lists. Under the hood it's using Net::RBLClient — iconic library behavior, no cap. 👑

What's the point? It lets you find out what the impact would be of filtering via various RBL's. Like, vibe check first, filter later.

The output report has two sections, and they are both important, so let's get into it.

Section one gives you one line per email message, showing:

  • Sending IP address
  • Sending hostname if any
  • Whether the IP is on a small list of possibly spammish netblocks
  • A list of letters representing RBL's which returned responses for this IP address

Section two contains one line for each of the top RBL's. And what counts as a top RBL? The ones that produced the most hits, obviously. They're listed in decreasing order of hits. Each line contains:

  • The letter assigned to the RBL — and heads up, "A" is the one with the most hits 👑
  • The domain name of the RBL
  • The number of hits from the RBL

💖 OPTIONS 💖

  • No options.

like... none. zero. the void. it just takes your mbox and goes. 🫶
